115200 bps was just confirmed on the CoCo *2*.  I couldn't do this 
with the tape version of CoCoNet because it runs in all-RAM mode on 
the 2, which doesn't allow the 2mhz POKE to work.  Now in ROM, it works.

I surely hope the CoCo 1's don't have an issue like you said.  Giving 
an old gray CoCo internet access is what I aim for.  I'm not sure if 
I have enough space to put 38400 bps routines in, but if needed I'll 
optimize the best I can and try to squeeze it in.
